Reducing the amount of software running on a system reduces its attack surface. Therefore a basic security measure for IGEL OS 10 is to remove all unused features.


To disable a feature:

  1. In the IGEL Setup go to System > Firmware Customization > Features.
  2. Deactivate all the features that you do not intend to use.
  3. If you do not use local printers on the endpoint device that you want to share with others, deactivate:
    • Printing (Internet Printing Protocol CUPS)
    • Printing (Line Printer LPD)
    • Printing (TCP/IP)
    • Printing (ThinPrint)
    Do not remove the Custom Partition feature if you have a custom partition that contains software or data for which you have no backup copy. After disabling the feature and a reboot the contents of the custom partition will be lost.
    Do not remove Fluendo Gstreamer Codec Plugins or Hardware Video Acceleration if you use sessions that make use of these features.
  4. Click Apply.
  5. Reboot the device.
